VV Catalog Flags (Catalog 31)
================================================================================
FIELD1 Explanation
10 VV 10 has the same coordinates as VV 29 in the VV Atlas. The
UGC was used to confirm that the coordinate is correct for VV
29 and erroneous for VV 10. The UGC position for VV 10 = UGC
10814 was adopted.
11 The VV position is substantially different (>400") from
positions for the object in other catalogs. The VV position
has been assumed to be in error because two or more other
catalogs agree on a different position. The UGC position has
been adopted.
12 Same as for 11, but the OSU position has been adopted.
13 The position in the VV Atlas, and the position listed for the
VV object in the OSU are in disagreement. The true position
has been established to be close to that of the OSU by the use
of overlay transparencies on the POSS. The OSU position has
been adopted.
14 Same as for 13, but the OSU position is not very good either,
so a new position has been measured (accurate to about 1').
